Specifications to Consider in a Pulley
Various pulley dimensions have to be taken into account before buying a pulley. They are:
* '''The diameter of the
sheave or drum''': Normally, larger the diameter of the sheave with respect to the rope diameter, longer the life of the rope, as a larger sheave reduces rope fatigue.\
* '''The diameter of the '''
'''rope''': The diameter of the rope depends on the maximum load you expect to haul or hoist using the rope. Hence you can choose the pulley based on the diameter of the rope and the maximum load you expect to haul.
* '''The depth and breadth of the groove''': The depth and breadth of the groove should comfortably accommodate the rope or belt with minimum friction. The groove could be an ‘A’ shaped groove or a flat surface with raised flanges on the edge. There are also sheaves without grooves.
